CHAIR OR STOOL ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 13, 19.10.

Application filed May 25, 1910. Serial No. 563,448.

To all whom it may concern:

Be it known that I, FIRMIN TAPSY NASH, a citizen of the United States,residing at Salem, ,in the county of Marion and State of Oregon, haveinvented certain new and useful Improvements in Chair or StoolAttachments, of which the following is a specification.

This invention relates to chairs or the like, and primarily toattachments for the same which are secured to the legs for preventingthe chair or the like from tilting over. It is especially designed foruse with high chairs used for infants which are so likely to be turnedover.

WVith the above and other objects in view reference is to be had to thefollowing description, claim, and the accompanying drawing in which:

Figure 1 is a perspective of the lower part of the chair having thepresent invention attached thereto in a manner in which the same is tobe used; Fig. 2 is a perspective of the attachment severed from thechair; Fig. 3 is a plan view of a clamp used in se curing the device tothe rear and side legs; Fig. 4 is an end elevation of the yoke of theclamp; Fig. 5 is a plan view of the clamp or device used on the frontleg; Fig. 6 is a longitudinal elevation thereof.

Referring more particularly to the drawing, A indicates the legs of achair, stool, or the like, to each one of which is secured thesupporting member B. Each supporting member is made from one piece ofwire which is bent upon itself at its middle, forming a standardcomprising spaced members 1 and 1, each of which is projected outwardlyand approximately at right angles from each other forming a flat foot 2.Each foot is formed by looping the terminal at a distance from thestandard, and twisting the extremity around the strai ht portionadjacent to the standard thus formed.

To the front leg of the chair is securely attached the supporting memberB by a pair of clamps 3, each of which is secured to the leg of thechair by piercing the same, and having each of its extremities clampedabout one of the spaced members of the standard retaining the same fromvertical movement. To the side and rear legs the supporting members areclamped by detachable clamps 4, each one of which comprises a yoke 5having its terminals bent inwardly to engage the standard, and a thumbscrew 6 passing through the elbow or curve of said yoke and having aswivel connection to a pressure block 7. The rubber washer 8 may beinserted between the pressure block 7 and the leg of the chair toprevent the chair from being scratched and the clamp from slipping. Itwill thus be seen the side and rear legs may be adjusted to a higher orlower plane than that of the front log by loosening the clamps 4 andadjusting the supporting members vertically after which same may berigidly secured in their determined position by the thumb screw 6. Itwill furthermore be seen that the chair will be difficult to tilt orturn over, due to the attachment of the present invention, thus makingit safer to all occupants.

To prevent the spaced members of the standard from spreading apart whichthey would have a tendency to do when supporting persons, a staple 3 issecured adjacent to the lower extremity of each leg and is adapted tobind about the said spaced members for the specified purpose. Thesestaples may be secured as shown in Fig. 1 or they may be secured as theclamps 3 are. It will be observed that by the staples the Whole deviceis greatly strengthened, thus making it more desirable for chairs. Eachstaple 3 is positioned close to the base of the leg of the chair andforms a sliding connection with the attachment. The clamps are securedabove the staple and due to their peculiar shape tend to spread thespaced mem bers apart as the yoke is drawn inward by the operating ofthe thumb screw. It will thus be seen that in the above operation thelower portions of the spaced members of the standard will convergeslightly and due to this action will be raised slightly from the floorat the outward bend. A resilient action is .thus obtained when the chairis being occupied, which action may be adjusted by the furthertightening or loosening of the clamps.

Having described this invention what is claimed as new is:

The combination with a chair embodying a supporting leg, of anattachment secured thereto comprising a single piece of wire bent uponitself centrally forming a standard, having spaced members, theterminals of said wire being bent outwardly and looped forming flat feeteach extremity be ing twisted about its respective outwardly bentstraight portion provided intermediate the loop and standard forreinforcing the 1 against the leg of the chair for the purpose same, astaple carried by the leg to permit herein set forth. 10 the sliding of.the standard therein, and i In testimony whereof I have affixed myclamps to adjustably secure the attachment signature in presence of tWoWitnesses.

v to the chair, each clamp consisting of a yoke F IRMIN TAPSY NASH.

having each of its terminals engaging one of Witnesses: said spacedmembers and a thumb screw HENRY J. WORKMAN,
